PL help me get started

I installed Express. It works well and I am able to get a response from ping using Aqua studio (which I intend to use), all running services. I just specified a SYSTEM password during installation. What should I do next to start? Services that are currently running, but this does not mean a database is created? or the schema is set yet?
Basic idea of just to start, so I think I'll be good to go

My goal is to practice, learn PL/SQL and oracle database administration...

Thank you very much

Welcome to the forums and in the world of the Oracle database.

Because you referenced "Getting Started", we know that you have already found and began to read the relevant documentation. Good for you! A surprising number of people skip "reading literature" - If you are already off the coast a good start.

Oracle XE and APEX take care of some typical details of administration for you. In the default of Oracle XE installation, your SID will be "XE".
The default database listening port is 1521. Knowing this, you can recognize the sections in "Getting Started" when they are used in establishing a connection to the database.

In Oracle, a "database" is a set of files, and an "instance" is a set of structures of memory and process/service running on a host. XE is your body in this case, that interacts with the database created during the installation. In a database instance, "diagrams" represent the two users and objects held by the users of the database (tables, views, PL/SQL, etc.). 'schema' and 'user' are somewhat synonymous in Oracle.

After "Getting Started", I suggest you continue on the links on the page of Documentation XE: "2 day s/n", then "2 day Developer's Guide. After that if one of the developer of the specific language Guides apply, you can look at those.

Aqua (I'm not familiar with this tool personally) it takes probably the SID (XE) Port (1521) and a name of user and password... This could be the user name of scheme / you see in the APEX, or could be another user that you create with the appropriate privileges in your data base (2 day s/n will explain everything you need to create another user and assign privileges.)

  • New to ID and you are looking for help in getting started

    Hello

    New ID, he bought the other day. Working with Adobe Creative Suite, DW, FW, PS and Flash sort.

    I ID like and would like to do some stationery namely cards biz, creation of letterhead etc..

    Someone at - it a good video tutorials on this subject they might recommend.

    ID "seems to" work a little differently to how I thought, only had a little go, so think I need a little time to see on how to use it.

    I find Adobe go of in for details, I'm just after the bases of the creation of the first stationery then will work in my view some of the other features it seems to offer.

    Thanks in advance.

    PNG is not the best possible format for images for printing, but much will depend on how the printing will be done. In general terms, printing images must be much higher tose Quen resolution used for screen display. To print on a desktop device you will want to "effective" resolution (resolution to the size, it will be printed, not the size, it has been saved) somewhere around 150-200 dpi for continuous-tone images. The press usually to 250-350 ppi. Line art must be in the range of 1200 dpi.

    Text is colored by applying a sample or using the color Panel. If you look at the color chart or the color Panel, or next to the colored boxes to the bottoom of the Toolbox, you will see a pair of buttons, one that looks like a T and another that looks like a square. When the T key on the color will be applied to the text. When the sqare button is active, it will apply to the frame. The two colored boxes represent the (solid box) fill color and stroke color (hollow box) and the one in front is active, similar to the foreground/background in Photoshop.

    Color for printing is quite tricky and depends on the method of printing once more. On a desktop device or a color copier, you can be pretty free with what you use (but don't expect an exact match for a spot color - or any other color if your monitor isn't calibrated and you don't have an output profile good - but this is a whole different debate), but on a press, you use either CMYK , which requires 4 plates and costly for small series or tones, each of them also require a separate plate, but are ideal for the type of color and logos.

    Take the advice of Bob. Spend time to Lynda.com and try to learn as much as you can about printing, too, if you want to work in color. More you know about the ink on paper easier design and the use of will become ID. If you can find a class at the local Community College or adult education, try also. InDesign is in fact a very complex program.

  • How to get started with Obj oriented AS3? (Flash help seems broken)

    OK, I won't be the noob who does not read the manual and ask stupid questions, but I'm stuck here. It's been long since I had no experience real flash (Flash 5 in depth) and a small Flash 8. But now, my work has led me in some flash work & I'm basically from scratch. I am trying to get just a simple SWF to load an external class and have the class retrun value of a method.

    I define

    package
    {
    public class Greeter
    {
    public function sayHello (): String
    {
    var host: String;
    greeting = "Hello World!";
    return of the vows;
    }
    }
    }

    in an .as file (which is located in the same directory as my .fla) then frame 1 of my time line, I have:

    var myGreeter:Greeter = new Greeter();
    mainText.text = myGreeter.sayHello("Bob");

    When I try and test the movie I get 2 errors:

    1046: type was not found or is not a constant of compilation: Greeter.

    Quote:
    Posted by: newsgroup user
    I get only one, which is the "Incorrect number of arguments. EXPECTED
    no more 0,' and the reason for this is that the sayHello() method
    is not configured to receive all parameters.

    Under most of the cases I would have been skeptical of the passage of an argument when nothing is defined, but I thought I had heard (way back to AS 2) AS being based on some sort of JavaScript rules so I thought maybe that didn't matter. And unfortunately, this error was not my fault for typing, its actually printed this way in the Flash help (see: getting started with ActionScript > example: creating a basic application).

    We appreciate that clarification, even if I didn't get the error you mentioned. The compiler has never had that long before he released on bail.

    2. you must register the Greeter Greeter.as class file

    OK, this has proved be the problem... Just on a hunch, I decided to look into the matter. Save the file as [greeter.as/i] errors but off [ Greeter.as/i] does not work. Flash is really sensitive with regard to file names? In any case, I'm a little better. Thank you very much.

  • WebServices - need help getting started...

    Hi all

    I am fairly new to Web services and Coldfusion I could use some help getting started. Creating the Web service has already been made, so I need to create a new one, so that the part is already done.  The existing webservice is written in .NET and I need to consume using Coldfusion. I think I have all the information I need from the creator (s) in the various XML files. There are a few examples of applications in the .xml file format in the information that was given, as well as a wsdl.xml file. Of my reading on Coldfusion and Web services is that they are consumed by the...

    < cfinvoke webservice = "yada.wsdl" method = "use" returnvariable = "returnedVal" > "

    and send arguments through

    < cfinvokeargument

    to the Web service that returns the data.

    But t that's where I'm wrong... It seems I should use the wsdl.xml file to connect to the Web service... is that correct? I have to place the wsdl.xml outside the Web root in IIS?

    Any suggestions are appreciated.

    If you try to refer to this wsdl file:

    Directory containing wsdl.xml

    .../wwwroot/mydir/WSDL.Xml

    Then, you must use a parameter like this:

    method http://localhost/mydir/WSDL.xml"="mywsdlmethod"returnvar ="data">

    « ? WSDL"is a ColdFusion function that uses the ability of ColdFusion to generate a wsdl file dynamically on the fly from a SWC file that is configured to be a web service.

  • HOW can I remove my Bookmarks Toolbar Firefox's "Getting Started" link? It wastes space and seems invulnerable to the attempted abductions.

    From the outset, I am on a MacBook Air, running Yosemite & the most recent Firefox Help. If your only interest in my question is for bash Macs, then (yawn) I'm not interested. If your interest is to help sincerely, then you have my interest as well:

    I'm stuck with a "Getting Started" Firefox link as the first 'signet' (left) on my bookmarks bar, I really want to delete: I was in the Apple computers (from the Apple] [e) & online since the mid-80s, so I'm hardly a naif in the digital world or Firefox newbie , so having a "Getting Started" link to life is ridiculous, AND I really need the space to accommodate MY choice! Then...

    I tried all ways recommended to delete unwanted bookmarks - Firefox, BUT when I pull down the "Show all bookmarks" command of bookmarks in the Menu bar, there is NO such thing as the "Getting Started" link, so I can't delete it there. I've even linked by clicking and dragging it out of the toolbar, but it does not (nor made more by dragging to the trash. Then, someone has idea of this insurgent link?

    You can try this?

    1. Open the Bookmarks Manager. In what is the Apple menu icon or the menu bar, click bookmarks > show all bookmarks.
    2. In the search bar search Favorites, type getting started.
    3. Delete the bookmark that opens.

    Hi ricklord303,

    You should take a look at the Knowledge Base How to set the home pagearticle.

    There are the steps in this article to reset your preferences on the default home page. I would try everything first to clear all strangeness. If it works, you can try to set your homepage again to your personal preferences.

    If this does not work you should look at this article on this specific issue and Preferences not savedarticle.
